ORDER NUMBER DOC 2303675
Ensure that the hose material is chemically resistant to the sprayed products.
Ensure that the product hose is suitable for the pressure generated in the device.
Ensure that the following information can be seen on the high-pressure hose:
– Manufacturer
– Permissible operating overpressure
– Date of manufacture
Make sure that the hoses are laid only in suitable places. In no case, should hoses be laid
in the following places:
– in high-traffic areas,
– on sharp edges,
– on moving parts, or
– on hot surfaces
Make sure that the hoses are never used to pull or move the device.
The electrical resistance of the complete high-pressure hose must be less than 1 Mohm.
Several liquids have a high expansion coe cient. In some cases their volume can rise with
consequent damage to pipes, ttings, etc. and cause uid leakage.
When the pump sucks liquid from a closed tank, ensure that air or suitable gas can enter
the tank to avoid a vacuum being generated in the tank itself. Thus a negative pressure is
avoided. The vacuum could implode the tank (squeeze) and can cause it to break. The tank
would leak and the liquid would ow out.
The pressure created by the pump is a multiplication of the inlet air pressure.
4.2.3 PRODUCT HOSES
4.2.2 GROUNDING THE DEVICE
In order to avoid electrostatic charging of the device, the device must be grounded.
Friction, owing liquids, and air or electrostatic coating processes create charges. Flames or
sparks can form during discharge.
Ensure that the device is grounded for every spraying operation.
Ground the work pieces to be coated.
Ensure that all persons inside the working area are grounded, e.g. that they are wearing
static dissipative shoes.
Wear dissipative gloves when spraying. The grounding takes place via the spray gun handle.
